Thus, chiral spin texture devices have several promising avenues to address critical scalability and performance requirements for next-generation memory,[1]}, [2]}, [3]} logic[4]}, [5]} and computing applications (Fig. 1).[6]}, [7]}, [8]} Plausible memory devices include MTJ-like devices that incorporate spin textures for multistate readout, and racetrack memory with electrically driven spin textures representing sequential memory bits. Further, chiral hardware holds immense potential for unconventional computing frameworks such as neural networks, reservoir and stochastic computing. To this end, challenges for materials engineering and device optimization remain, and will have to be addressed to improve the performance of chiral spin texture-based memory and computing technologies. In this review, we first describe the evolution of spin textures in ferromagnetic thin films fabricated and imaged using a range of state-of-the-art microscopy techniques. Next, we provide a broad overview of their behaviour in response to extrinsic factors arising from geometric contributions, inter-wire interactions, thermal stimuli and current injections. Finally, we discuss their functionalities in racetrack memory and brain-inspired neuromorphic devices. By leveraging novel chiral material and device approaches, exciting directions for emerging chiral spintronics technologies are charted.
